Acknowledgements

We would like to thank our wives Sue and Bridget for all their patience and help with the preparation of this book.

Discussions with colleagues and clients have provided many of the insights that we have been able to develop. Feedback from the carefully selected group of people who have read the book for us in advance of publication has been extremely valuable. We would like to thank everybody involved for their help and advice, particularly Dr Jill Armfield, Roger Smith, John Tew and Colin Webb who commented on the book for us before the manuscript was finalized.
